(5/7)^10 · 1.4^9

ik this alr up here, but the answer is 0.714286

Step-by-step explanation:

Here's why:

First, im put the problem up first.

(5/7)^10 · 1.4^9

Then ima multiply (5/7) 10 times and keep 1.4^9 and here's why

if you don't multiply the exponent your answer will be wrong and you will be confused. So always use the exponent to simplify your answer. if you do 1.4^9 already. you will not find the right answer to simplify. so don't do yet,because that's on the next step

so here's what i got

5/7=9765625/282475249(1.4^9)

Then i will multiply 1.4 9 times in order to find the answer

1.4^9=20.661047

So now we will do the rest

9765625/282475249 (20.661047)

the answer is 0.714286

so now the answer is 0.714286

Hope The Great Devourer help :)

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
